FIELD OF THE INVENTION

The present invention relates to a method of, and system for,controlling access to a plurality of communications sessions involving aplurality of users, and is particularly, but not exclusively, suitablefor allocating a group of users to a communications session based on amatch between characteristics of a given communications session andcharacteristics associated with the group.

BACKGROUND INFORMATION

As is well known, communications networks provide a means for users tocommunicate with one or more other users. Users of a communicationsystem are typically provided with numerous services, such as calls,data communication such as messaging and/or multimedia services, orsimply provide users with a gateway to another network, such as theInternet. In relation to any one service, various communication systems,such as public switched telephone networks (PSTN), wirelesscommunication systems, e.g. global system for mobile communications(GSM), general packet radio service (GPRS), universal mobiletelecommunications system (UMTS), wireless local area network (WLAN) andso on, and/or other communication networks, such as an Internet Protocol(IP) network, may simultaneously be concerned in providing a connection.An end-user may access a communication network by means of anyappropriate communication device, such as user equipment (UE), a mobilestation (MS), a cellular phone, a personal digital assistant (PDA), apersonal computer (PC), or any other equipment operable according to asuitable network protocol, such as a Session Initiation Protocol (SIP)or a wireless applications protocol (WAP) or a hypertext transferprotocol (HTTP). The user equipment may support, in addition to call andnetwork access functions, other services, such as short message service(SMS), multimedia message service (MMS), electronic mail (email), Webservice interface (WSI) messaging and voice mail and one-way messagessuch as WAP PUSH messages.

Communications services involving more than two users are generallyreferred to as group communications services, and include the“push-to-talk over cellular” (PoC) service also known as the PTT(push-to-talk service), the instant messaging (IM) service, IRC(“Internet Relay Chat”), and the ICQ (“I Seek You”) service. In the caseof the IM service, users are allowed to send messages to one or more ina list of predetermined users (a so-called “private list”) in aconversational mode, and because they are transmitted “instantly”, thetransfer of messages back and forth is fast enough for participants tomaintain an interactive conversation. The IRC service is a system forchatting that involves a set of rules and conventions and is implementedvia client/server software. An IRC client can be downloaded to a user'scomputer, and the client is then used to connect to an IRC server in anIRC network to start or join an IRC chat group. The fourth groupmessaging application, ICQ (“I Seek You”), is a client application thatprovides information as to which “friends” and “contacts” are alsoonline on the Internet, pages them, and operates so as to coordinate a“chat” session with them. The IM system is similarly arranged togenerate alerts whenever a member of a given private list is online.

When designing a service, the objectives of the service provider—interms of their effect on end users—have a significant bearing on thetechnology that is selected to support the service. For example,services that are designed to deliver information to a selected group ofusers (with a view to triggering a particular action to be taken on thepart of the group members) make use of technology that is designed tomatch characteristics of the users with those of the information so asto improve the match between what the user receives and what the userwants to receive. Typically such information is delivered from a singlesource to many recipients, and any subsequent interactions proceedbetween the recipient and communications devices related to theinformation source.

As will be appreciated from the foregoing, in addition to transmittinginformation from one→one and one→many recipients, information can bedistributed between members of a group so as to encourage discussionbetween—and thus impact on—group members, thereby increasing theeffectiveness of the information. As described above and ininternational patent application having publication numberWO2006/027407, known group communications methods involve discussionsbetween predetermined or specified members of a group. Thus whilst knowngroup communications services provide a means of increasing the impactof information on users, the extent of this impact is neverthelesslimited to that achievable within a closed group of recipients.

SUMMARY OF THE INVENTION

In accordance with one aspect of the present invention, there isprovided a method of controlling access to a communications session.Embodiments of the invention thus provide a means of selecting acommunications session, or discussion forum, to host a group discussionbetween members of a group of users, and thus advantageously provide ameans of controlling the context for discussion among the group members.

The members of the group are preferably notified of the selectedcommunications session via a WAP message, which contains a link to thecommunications session, while selection of the communications sessioncan be triggered by receipt of a short message—such as an SMSmessage—from a member of the group. The SMS message convenientlyidentifies the group and can contain a line of text or image that themember wants to pass on for discussion. Since the majority of terminalsare capable of sending and receiving SMS and WAP messages, the terminalsof participating group members do not need to have any bespoke softwareapplications installed on their handsets in order to make use of the newservice.

According to another aspect of the present invention there is provided amethod which provides a means for groups of users to take part incommunications sessions involving participants of a publicly accessibleand interactive communications session, and thus provides a mechanismfor information to be discussed and disseminated—in a particular periodof time—by a wider audience than is possible with present methods.

Further features and advantages of the invention will become apparentfrom the following description of preferred embodiments of theinvention, given by way of example only, which is made with reference tothe accompanying drawings.

DETAILED DESCRIPTION

As described briefly above, embodiments of the invention are concernedwith coordinating access to a communications session, specificallycoordinating access by a predetermined group of terminals to one of aplurality of available communications sessions.

Identification of the group members and the methods of providing memberswith access data for enabling access to the communications session willbe described in detail later in the description, but first a descriptionof the infrastructure needed to coordinate access to the communicationssession will be described.

FIG. 1 shows an example of a data messaging system 100 within whichembodiments of a first aspect of the invention operate; the arrowsindicate data flows within the data messaging system 100 and the objectsindicate components of the data messaging system 100. This Figure showsan arrangement of network components suitable for the delivery of WAPmessages, Short Message (SMS messages), Multimedia messages (MMSmessages), bespoke messages in the form of GPRS data and/or streameddata; as will be appreciated, the specific arrangement of the datamessaging system 100 is dependent on the type of message being used tofacilitate the coordination.

In the arrangement shown in FIG. 1, a terminal T1 communicates withvarious network devices within the data messaging system 100. Theterminal T1 may be a wireless terminal such as a mobile phone, a PDA ora Laptop computer, or it may be a fixed terminal, e.g. in the form of aPersonal Computer. In the arrangement shown in FIG. 1 the data messagingsystem 100 comprises: a WAP gateway 7, which is typically a networkoperator's WAP gateway; a distribution server S1; and a database DB1,arranged to store at least some of:

-   -   data in respect of users of the data messaging system 100,        including data identifying interests and characteristics of        individual users and groups of users;    -   data in respect of terminals such as terminals T1, T2, T3 and        T4;    -   data in respect of tagging content, including image (static,        dynamic and/or interactive images), alphanumeric characters and        content control information, the data having been provided by        various content providers CP1, CP2; and    -   communications sessions data in respect of communications        sessions, including: data identifying sponsors; demographic        requirements (in terms of types of users who are preferred        participants of a given communications session); priority        information; and status information (e.g. active, inactive        etc.). The communications sessions, and thus sponsor,        demographic and priority information, can be related to the        content providers CP1, CP2.

In one arrangement the distribution server S1 and the database DB1 arelocated within a proprietary network, which means that they operateindependently of any specific network operator and can be shared acrossa plurality of network operators. Using techniques known in the art, thedatabase DB1 can store the preference and demographic data that are usedto control selection of a communications session, or discussion forum,as described below.

The functionality of the distribution server S1 will now be describedwith reference to FIGS. 2 and 3. In addition to standard CPU, memory,data bus, Input/Output ports, data storage, and operating systemprograms, the distribution server S1 comprises certain bespokefunctional components, namely:

-   -   tagging data selector software component 201 for selecting        tagging data from the database DB1;    -   message analyser component 203 for identifying group members        that are to be joined with the selected communications session;        and    -   outgoing message generator component 205 for selecting a        communications session to which the group members are to be        joined and for creating messages that include access data        enabling recipients of a given message to join the selected        communications session.

In a first embodiment the incoming (or initiating or originating)message M1 is an SMS message originating from the terminal T1; theoriginating message M1 contains a message body and carries details of agroup of recipients such that the incoming message analyser 203 canidentify the group identifier from the message. In one arrangement,during message creation the sending terminal T1 prompts the sendingsubscriber to select a group from a preconfigured list of groups storedon the terminal T1, causing the terminal T1 to create an SMS messageidentifying the selected group and having a format compatible with theformat requirements of the message analyser component 203. Thisarrangement presupposes that the message analyser component 203 hasaccess to the predetermined groups and members thereof.

In an alternative arrangement, the user of the terminal T1 enters anidentifier for a group manually within the content of the SMS messageM1; for example groups could be identified by numbers or by specialcharacters, such as: “% This is a group message”, “#This is a groupmessage”, “&This is a group message”, where first one would be forwardedto group identified with %, second with # and third with &. As for thefirst arrangement, the group members corresponding to a given characterwould be accessible to the message analyser component 203 (such specialcharacter definitions groups could be specified via web interface).

In a yet further arrangement, and instead of selecting a groupidentifier that relates to a predetermined set of group members, thesending terminal T1 could prompt the user to simply select “Group” froma list of possible message types, without selecting a specific groupidentity. In this arrangement the terminal T1 would create an SMSmessage identifying that message M1 is intended to spawn creation of agroup message, but identification of the group members would be aprocess performed by the message analyser component 203, and thus inreal time rather than based on any predetermined group lists. In a yetfurther arrangement the terminal could be configured to analyse thecontent of individual messages, and for those whose content isdetermined to be identical to that of other messages, the terminal couldsend out a single message with an identifier indicating the message tobe of a group type.

The message M1 could include additional information entered at terminalT1, such as keywords identifying subject matter of particular interestat the time of sending the message, and these can be used by the taggingdata selector 201 when selecting the communications session to which thegroup members are to be joined.

In any of these arrangements, the destination address of the SMS messageM1 would be the network identity of the server S1.

For an arrangement in which individual messages are sent out toindividual recipients (without analysis by the terminal T1 in the mannerspecified above), the message analyser component 203 would either bedirectly associated with SMSC 3, or the SMSC 3 would be provisioned withspecific forwarding instructions in respect of individual recipients soas to ensure that the individual SMS messages M1 are forwarded to theserver S1. Once received, the message analyser component 203 wouldanalyse the content of individual messages so as to determine thosehaving identical content, and deriving a group on the basis of thecontent of the messages M1.

It will be understood from the foregoing that the function of themessage analyser component 203 is at least to derive the identities ofgroup members to whom communications sessions invitations are to besent. These process steps are indicated in FIG. 3 by S3.1 and S3.3.

Turning now to the creation of messages inviting group members tocommunications sessions, the outgoing message generator 205 is arrangedto create individual invitation messages M2 a, M2 b, M2 c, one for eachmember of the group identified by the message analyser component 203. Inone embodiment these messages M2 a, M2 b, M2 c are embodied as WAPmessages; WAP is a convenient choice of format for the outgoing messagesbecause it allows links such as URLs and the like to be included withina message, these being displayed as a selectable object on a recipient'sterminal which, when selected, cause the terminal to retrieve data fromthe network address associated with the object.

As described above, embodiments of the invention are concerned withcoordinating the joining of members of a group to a communicationssession, and the links that are inserted into a given WAP message M2 a,M2 b, M2 c created by the outgoing message generator 205 include linksto discussion forums and the like. Preferably at least some of thediscussion forums are publicly accessible so that, in at least someembodiments, whilst a group identifier is used to select individuals toinvolve in a communications session, the communications session to whichthey are invited to attend is not limited to group members only. Thisdiffers significantly from conventional methods such as those describedin international patent application having publication numberWO06/027407, where the group identifier serves both to identifyindividuals to involve in a given discussion, and to define theparticipants in the discussion. Selection of a communications sessioncan be dependent on attributes such as keywords specified in theinitiating message M1 (if available), and/or time of receipt of theinitiating message M1, and/or profile data corresponding to the groupand/or one or more of the identified group members. Accordingly, uponreceipt of the group member identities, the outgoing message generator205 is arranged to access the database DB1 and retrieve interests andpreference data corresponding to at least some of the group and/orindividual group members, and to compare these data with attributes ofcurrently active and accessible communications sessions. The attributesof a given communications session include a set of demographicrequirements, these having been specified by the host of a givencommunications session and being matched against the preference andinterests data corresponding to individuals of the group G (or the groupitself), thereby effectively controlling which types of groups areallowed to access a given communications session. In addition theattributes can include priority information, this having been specifiedor negotiated by a content provider CP1, CP2 (for example) and beingused by the outgoing message generator 205 when selecting a specificcommunications session from those available.

An example outgoing, or invitation, message M2 a including a link 401 toa communications session is shown in FIG. 4: the link 401 is embodied asa selectable object and is identifiable from the text “Press here tochat!”

The outgoing message generator 205 can also cooperate with the taggingdata selector software component 201 so as to select and insertinformation tags (such as those identified by reference numerals 403,407) into the invitation messages M2 a, M2 b, M2 c. The tagging softwarecomponent 201 is arranged to select image and/or text and/or audioand/or video tagging data on the basis of demographic data correspondingto one or more of the identified group members and from the repositoryof tagging data stored in the database DB1 and/or the text containedwithin the initiating message M1. For the example shown in FIG. 4, itcan be seen that the text 405 of the initiating message M1 has been usedto select both the image tag 403 and the text tag 407: the invitationmessages M2 a, M2 b, M2 c include the text 405 included in theinitiating message M1, together with information as to the origins ofthe invitation messages M2 a, M2 b, M2 c (“Message from Pete . . . ”)thereby providing suitable context for the tag data 403, 407 when theinvitation message M2 a is reviewed by a recipient. The foregoingmessage creation process is indicated generally in FIG. 3 at step S3.5.

In view of the fact that the tags 403, 407 are included with the link tothe selected communications session, it will be appreciated that thesetags 403, 407 can be used to steer group discussions within thecommunications session towards the subject matter of the tagging data,for example with incentives in the event that any participant of thegroup communications session purchase certain goods—from certainproviders—during the communications session (or within a specifiedperiod thereafter).

Furthermore, since the link 401 is the trigger for the IM chat session,the tags 403, 407 accompanying the link 401 essentially serve toannounce or promote the selected communications session. Thus in atleast some embodiments, the data to be selected for inclusion in a givenmessage are advertisement data, and in the case of the advertisementdata relating directly or indirectly to the communications sessionassociated with the link 401, the tags 403, 407 could identify a sponsorthereof.

Once the WAP messages M2 a, M2 b, M2 c have been created, they are sentto the recipients identified at step S3.3 via the WAP gateway 7 (stepS3.7), as is known in the art. It is to be noted that whilst not shownin FIG. 1, a WAP message is also preferably sent to the terminal T1 fromwhich the initiating message M1 was received (in this example, Pete'sterminal).

The transmission of the WAP messages M2 a M2 c marks the end of theinvolvement of the distribution server S1, since selection of the link401 is transmitted to network components associated with the link, andthis process is independent of the distribution server 51. Thus, ifactivation of the link 401 results in a HTTP request message to betransmitted to a web server running an IM chat session for example,subsequent messages would be transmitted in accordance with IM and itsassociated protocols (step S3.9).

Whilst in the embodiments described above the message M1 is an SMSmessage, it is to be understood that message M1 could alternatively be aUSSD, MMS, email or any other type of message capable of identifying agroup of recipient terminals. Similarly, whilst in the above embodimentsthe outgoing messages are embodied as PUSH WAP messages, they couldalternatively be embodied as MMS messages, SMS messages with link intext form, bookmarks to mobile terminal, e-mail, voice call, broadcastmessage using cellular networks (such as Multimedia Broadcast/MulticastService (MBMS) over Wideband Code Division Multiple Access (WCDMA)) orbroadcast messages using broadcast networks (such as Digital VideoBroadcast—Handheld (digital TV) (DVB-H), Integrated Services DigitalBroadcasting—Terrestrial (ISDB-T), Digital Audio Broadcasting (DAB),Forward Link Only (Qualcomm) (Flo), Digital Multimedia Broadcasting(DMB), Radio Data Service (RDS) channel of radio network to mentionfew), any multicast or broadcast IP session indicator protocol.

In the above embodiments, access to a communications session isdescribed in relation to a single group. However, selection of acommunications session could be made on the basis of the identity—andthus demographic data—corresponding to groups that have already beennotified of a communications session. Thus in addition to reviewingpriority and demographic requirements of a given communications session,the outgoing message generator 205 could be arranged to review theidentity of groups to whom invitation messages have previously beensent, and compare the demographic data between the respective groups inorder to select a communications session for the subsequently requestinggroup members.

The above embodiments are to be understood as illustrative andnon-limiting examples of the invention, which is concerned withfacilitating access to discussion forums by predetermined groups ofusers. It is to be understood that any feature described in relation toany one embodiment may be used alone, or in combination with otherfeatures described, and may also be used in combination with one or morefeatures of any other of the embodiments, or any combination of anyother of the embodiments.
